HoRToN, ot'- Windsor,'oi` the county of Windsor, and State of Vermont, `have invented a new and useful Stove or Furnace for generating heat and giving light; and do hereby declare the same tobe fully described inl the following specification and represented in lthe accompanying drawings, of Which-,- f g Figure 1 is a vertical and longitudinal section of it.

i Figure 2 is a horizontal section, taken through its fuel-chamber.

Y Figure 3 is a horizontal section, taken through its lantern.

h Figures 4 and' are hereinafter described. y y In -sucb drawings, the fire-place A is represented as ra. space comprehended between two concentric and A tubular cylinders or linings ab, made of lire-brick orother proper dre-resisting medium or composition.

Such lire-place is provided with an` annular grate, c, which may besupported so as to enable it to be re- `volved,-more orless, back and forth, so as to shake ashes from the fuel while it may be ,resting on such grate.

This grate is" placed over an inclined chute or plane,

d, which terminates over au ash-chamber, c,and leads.

the ashes into ,such chamber. u Y A metallic pipe, f, rises within and is encompassed bythe inner tubularlining a, and opens at bottom out of an air-'receiving chamber,`g,` which is disposed in rea.r,of` the ash-chamber, and is provided with a register, h, or series of airy-inlets, and a valve or valves The said air-chamber g also opens into another airchamber, t', over and on top of which the inner firebrick lininga is supportedl This lining is grooved vertically, as shown at 7c 76,'. &o.',ieach `groove being provided with a series of holes oropenings, 7 leading from it through the lining, and opening into -the fireplace or fuel-chamber, the whole being so that air from the `chamber t may flow up through the grooves of the lining, and through the openingsl, and thence into From the` chamber t' a series oi' pipes, in, radiate, and open communication .between such chamber and another concentric space or` chamber, n., which, at top,

`d encompassed by the outer` case o ofthe stove, haA vertical channels p p made in its outer surface.`- i l It also has a seriesoi' horizontal channels, q q, formed thereon, such channels being provided with passages or lholes r r leading laterally from them into the fuelchamber. ,Air passing from the chamber i, through the pipes 'm1, into tbevchamber n, will\tlow therefrom through the channels ofthe outer lining, and thence into the fuel-chamber.

is Surmounted by the y lire-brick lining l). This Over the fuel-chamber is a ame-chamber, s, which, atits sides, is provided with a series of fuel-supply openings, t, cach of which has a door, u, to it.

Out of the top ofthe fuel-chamber a series of hollow pyramidal frusta or ga`s-burners, w w w, is led up into a shallow air-chamber, x, into the middle of' which the tube j' opens. v

Over such burner there is an opening, y, made through the top z of the' air-chamber x,

' Fig. 4 is a top View of the said air-chamber top, with lits openings and the burners thereof.

rihe-top z constitutes the bottom `of a lantern or chamber, a', formed with panes b of glass or mica. inserted in its sides and top.

` @discharge-pipe, c', leads out of the dame-chamber and into a'pipe, d', extending from the top of the lan. tern,and opening out of such' lantern. There is a damper, e', iu the lower part of the discharge-pipe c', and there is also a damper, g', within the lower .part of the pipe d,and below the junction of' such pipe with the pipe c'.

Instead of the-seriesof gas-burners arranged as described, 'I` contemplate a continuous burner, made as shown in,y transverse section, in iig. 5;

i It consists of a cylindrical case or chamber, a", providedwith a conical top, and having a foraminous bottom. This chamber or case is to be arranged within the upper part of the flame-chamber, and with a narrow space between the two and surrounding the aircase a2. f

The air flowing from the pipe f directly into the case a? will be discharged through the holes of it-s bottom into the flame within the ame-chamber, and rising of the dame-chamber, especially those of them which may escape into the lantern. ,-Bymeans of the lantern, I not only get heat from the llame of the burner or burners, but light with such heat will be radiated from the dame through the sides of the lantern. Such light will illuminate the objects which may surround the stove or furnace.

. Fuel of any proper kind may be burned within the' fuel-chamber, it being supplied with air through the grate and through the linings, as described.

Thecombustible gases escaping into the flame-cham# ber will be more o1' less burned therein. Such'of them as may pass therefrom up through the burner or burners will be. there enlamed, and by receiving additions of atmospheric air, heated more or less in its passage to them, will be burned, and in a state of flame will enter the lantern, and produce the eii'ccts as stated.V

The waste volatile products'will flow off through the escape-pipe of the lantern.

` When the fire is first kindled, the damper ofthe lantern-pipe should be closed, and that of the exlt-pipe of the flame-chamber should be opened. Thus a diand conveying-chambers g i n, andthe central air-pipe reet draught from the dame-chamber will be eeoted. v f, connected as described.

I claim- Also, the combination and arrangement of the series The combination as well as the arrangement of the of gas-burners w with air-conducting space or chamlantem al, one or more gas-burnersw and the air-supber @provided with openings y, arranged with such plying passages thereof1 substantially as described, with burners in manner as described. the furnace or fuelfehamber.
